21 # This is the libgcc host-specific configuration file
22 # where a configuration type is mapped to different system-specific
23 # definitions and files.  This is invoked by the autoconf-generated
24 # configure script.  Putting it in a separate shell file lets us skip
25 # running autoconf when modifying host-specific information.
26
27 # This file bears an obvious resemblance to gcc/config.gcc.  The cases
28 # should be kept similar, to ease moving library-specific settings
29 # from config.gcc to this file.  That is also why tmake_file is
30 # left as tmake_file, rather than hmake_file, even though this library
31 # switches on ${host}.
32
33 # This file switches on the shell variable ${host}, and also uses the
34 # following shell variables:
35 #
36 #  with_*               Various variables as set by configure.
37
38 # This file sets the following shell variables for use by the
39 # autoconf-generated configure script:
40 #
41 #  asm_hidden_op        The assembler pseudo-op to use for hide
42 #                       lists for object files implemented in
43 #                       assembly (with -fvisibility=hidden for C).
44 #                       The default is ".hidden".
45 #  cpu_type             The name of the cpu, if different from the first
46 #                       chunk of the canonical host name.
47 #  enable_execute_stack The name of a source file implementing
48 #                       __enable_execute_stack.
49 #  extra_parts          List of extra object files that should be compiled
50 #                       for this target machine.  This may be overridden
51 #                       by setting EXTRA_PARTS in a tmake_file fragment.
52 #                       If either is set, EXTRA_PARTS and
53 #                       EXTRA_MULTILIB_PARTS inherited from the GCC
54 #                       subdirectory will be ignored.
55 #  md_unwind_header     The name of a header file defining
56 #                       MD_FALLBACK_FRAME_STATE_FOR.
57 #  sfp_machine_header   The name of a sfp-machine.h header file for soft-fp.
58 #                       Defaults to "$cpu_type/sfp-machine.h" if it exists,
59 #                       no-sfp-machine.h otherwise.
60 #  tmake_file           A list of machine-description-specific
61 #                       makefile-fragments, if different from
62 #                       "$cpu_type/t-$cpu_type".
63 #  unwind_header        The name of the header file declaring the unwind
64 #                       runtime interface routines.
